I can almost feel the icy stares coming out of the courthouse in London, where prosecutors delivered their opening statements in the insider trading trial of not one but two girlfriends of former Mizuho International Plc investment banker Thomas Ammann.

According to reports out of the UK, Ammann had inside information about a takeover of a Dutch photocopier company called Oce and encouraged two different girlfriends of his to invest in Oce prior to the takeover--and to pay him half of their profits. One of the girlfriends purchased 1 million euros ($1.3 million) of Oce securities, and doubled her money. The other made 65,000 pounds on a 39,000-pound stake.

While Ammann has already pleaded guilty to charges of insider trading and to charges of something called "encouraging insider trading," the two girlfriends are taking their cases to trial. FSA lawyer Amanda Pinto told the jury that “each of the girlfriends considered Thomas Ammann to be their boyfriend, and neither knew of the other.” Oooooooffff. It is unclear whether Ammann will be called as a witness in the case. I am pretty confident that hell hath no fury like two former girlfriends of the same guy who didn't know about each other and now are both being charged with insider trading, however. 

Prosecutors have gotten their hands on the personal diary of one of the girlfriends, Jessica Mang, which confirms that Ammann advised her to invest in Oce. It also includes a passage in which Mang's friend "expressed her disapproval [about the trading] and kept calling it insider dealing.” Mang wrote, "“Really? Is that necessary? Increasingly prissy.” She added that she found the idea of having to pay Ammann half of the profits "a little demeaning too. I'd feel like I pay him for his companionship.”
